While grabbing in the Web in order to look for an explanation to this picture I found those words : "...When we arrived at Mauthausen, the SS officer who received this convoy of about 1,200 Frenchmen informed us in the following words, which I shall quote from memory almost word for word: "Germany needs your arms. You are, therefore, going to work, but I want to tell you that never again will you see your families. Who enters this camp, will leave it only by the chimney of the crematorium."... And this is the chimney this survivor talks about. .
